The IRS today announced that it plans to update the International Data Exchange Service (IDES) data preparation process to improve security.
According to today’s release, beginning 11 July 2016, the IRS will change the cipher mode from Electronic Code Book (ECB) to Cipher Block Chaining (CBC), and IDES will no longer accept data packets encrypted with the ECB cipher mode. The IRS released the data packaging code samples to help users update their systems to support the CBC cipher mode.
IDES opens for testing on 16-30 June 2016, and the test environment will only support the CBC cipher mode. The IRS stated that data packets transmitted with the current ECB cipher mode will be rejected.
